I've found this file showing up on computers that have nothing in common with a Toshiba laptop (i.e. my custom machines). I'm not sure how it got there. But it seems to show up in the startup menu about the same time other apps begin to fail. All that I have read about it shows that it can show up in a number of places. After removing it (including registry entries) and reinstalling the affected apps seems to clear things up.
